The AI Uprising destroys society as we know it. Banking is wiped out overnight. No internet, phones, or electricity. Anything “smart” or “connected” turns against humans. The military’s SoldierBots have one function--seek and destroy. Block is a simple CleanerBot programmed to clean and serve hotel guests. Forced to leave his city, he must avoid dangerous SoldierBots and find a new hotel he can call home. But when Block discovers a human infant, his surprise attachment to the girl compels him to protect her while traveling across the metal infested wastelands of America to a safe haven. Without his help, the abandoned baby could die before they reach safety. When he encounters Nova - a surly soldier who becomes an unlikely ally - they must tackle the biggest challenge of their lives. Together, they face mortal danger from bands of scavengers, militaristic SoldierBots, and Combat Mechs. A cyborg Bounty Hunter will stop at nothing to find Block and the child - an infant who holds the key to humanity’s future.
